A1221ELHLX-T Overview
ldeally, the magnetic switch should be packaged in the Tape & Reel (TR) for protection against damage. Magnet switches are packed in SOT-23W packages for safety reasons. As a maximum current, the magnetic switches can supply 4mA. In operation, these switches can output a maximum current of 25mA. In order for the switches to function, they have pins 3. As far as terminations are concerned, there are 3. The current output of the switches should, in general, be 25mA.
